SET(M) app made through SCS - missing marriage certificate

I didn't think of it at the time, but now I am a bit worried.

I made my application for SET(M) using the settlement checking service at Huntingdon. I didn't bring my marriage certificate (Oops!), but the person checking my application called someone (I'm guessing this was someone at the Home Office) and she was told to continue checking my application and that the HO may request my marriage certificate from me at a later date.

I've been thinking about it, and the marriage certificate is an important document for SET(M) and I'm wondering if I should contact the number for information on where to send my marriage certificate -or- if I should stop worrying about it and wait and see what happens.

Any advice would be appreciated.

If you used it in a previous application they'll have a copy so not important, if they want it they'll request it.

Thanks!
